I claim 1. A bottle capping device of the character described, comprising an open ended casing, a piston reciprocable vertically in said casing and formed to receive a plurality of bottle caps, means operative upon the upstroke of the piston to remove a cap' from the piston and transfer the same to the casing, and means carried by the casing for conveying the re moved cap to a position in the casing beneath the piston.

2. A bottle capping device comprising an open ended casing, a piston reciprocable vertically in'said casing and formed to provide a cap magazine; a cap removing device carried by said piston and operating during the up stroke of the piston for shiftinga cap from the magazine to the casing, and means carried by the casing for receiving and conveying a removed cap to position to be acted upon by the piston. V V v 3. A bottle capping device, comprising a cylinder; a piston reciprocable vertically in said cylinder, said piston being chambered to receive bottle caps and further having a lateral discharge opening, an ejector carried by the piston and operating upon the up stroke of the piston to force a cap from the I piston chamber outwardly through said l at eral discharge opening, and means carried and arranged at aside of the cylinder to re ceive a ca'p from the discharge opening to convey it and a point beneath the piston.

4. A botle capping device, comprising a cylinder, a piston reciprocable in said cylinder, said piston being chambered to receive bottle capsand further having a lateral opening for the discharge of caps, an oscillatory ejector carried by the piston adj aeent the lateral opening to force caps therethrough,

means carried the cylinder and engaging the ejector to oscillate the same upon move- 'ment of the piston, and means'carried by the cylinder to receive an ejected and convey the same to position beneath the piston.

5. A bottle capping device comprising an open ended casing, a piston reciprocable vertically in said casing and formed to provide a 'cap magazine having a lateral discharge opening, a laterally oscillatory cap ejector having a cap engaging projection at one side thereof and operative on the upstroke of the piston to engage and force a cap from the magazine outwardly through the discharge opening, and means carried by the casing for receiving and conveying a rernovedcap to a position to be acted upon by the piston.
